How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
How do you separate magnetic and nonmagnetic particles?
You can separate magnetic and nonmagnetic particles using a magnet. The magnetic particles will be attracted to the magnet and can be easily separated from the nonmagnetic particles. This method is commonly used in industries such as mining and recycling.
Is a pencil magnetic or nonmagnetic?
Yes a pencil could be magnetized. But it could only be magnetized with pencils only not a magnet.
Why might a permanent magnet become unmagnetized if it is dropped?
Dropping a permanent magnet can cause the magnetic domains within the material to become misaligned, reducing its overall magnetic field strength. This process can demagnetize the magnet if it is subjected to a strong enough impact.
Does nonmagnetic materials have equal number of protons and electrons?
Yes, nonmagnetic materials have equal number of positive and negative charges. Which is why neither end of a magnet will attach.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is a Refrigerator magnet a Permanent magnet?
No, a refrigerator magnet is not a permanent magnet. Refrigerator magnets are usually made of soft magnetic materials that become temporarily magnetized when in the presence of a magnetic field, allowing them to stick to the refrigerator. Permanent magnets, on the other hand, retain their magnetization over time without the need for an external magnetic field.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
What might happen if you drop a permanent magnet or strike it hard?
A permanent magnet may become unmagnetized because a shock it will have.
